Radiant Barriers are becoming more commonplace and people are realizing just how much more effective radiant barrier is compared to the traditional mass insulation.
Conventional mass fiberglass insulation, no matter how thick, has almost no ability to block radiant heat energy which can account for as much as 93% of summer heat gain and up to 75% of winter heat loss. These products are only designed to slow down conduction heat energy.
If you are only relying on an R-valued material to insulate against radiant heat gain/loss remember, these types of insulation are not designed to stop the radiant energy like a high quality radiant barrier like Energy Q's.
Energy Q's Reflective Thermal Barrier, if properly applied, will increase comfort levels and lower utility costs by reducing heat loss or gain, as well as, increase the efficiency and energy consumption of equipment.
